Rails 应用加载速度极慢

Question

我在 heroku 上有几个免费层 rails 应用程序运行ning 运行非常好，我没有遇到任何问题。

但是这个

kearns.herokuapp.com

加载速度太慢了！ dyno 不休眠，因为我每隔几分钟就会对它发出 ping 声。

如果有人有时间，他们可以快速访问一下，看看他们认为它可能是什么吗？非常感谢！

// If you'd like to override bootstrap's own variables, you can do so here as well

Answer 1

您可以在 heroku 上添加免费 new relic 插件并深入检查发生了什么，您的应用程序如何响应请求。

Answer 2

哇，您的 application.css 文件（http://kearns.herokuapp.com/assets/application-c515eba896f4bd53f59a05b117a195e0.css 现在）超过 16 MB。看起来你在那里包含了实际的图像文件 - 它应该只有图像的 url。
